wherein the wheel shafts are movable in the upper and lower directions in a predetermined range, and the wheel shafts are pressed with the right and left edge portions by a biasing force of the biasing member so that the wheels are in contact with a ground.
- 9. A running toy, comprising:
a steering device for a toy, comprising: first and second turning members to turn respective steering wheels; a connecting member to connect the turning members with each other; a coil and a magnetic body to move the connecting member between first and second positions by carrying a current to the coil; and a torsion spring to keep the connecting member at a neutral position between the first and second positions, when the current is not carried in the coil, wherein the turning members are turned by moving the connecting member between the first and second positions to change a direction of the steering wheels, wherein one of the coil and the magnetic body is provided on the connecting member, and the other of the coil and the magnetic body is fixed to the toy, wherein the connecting member is moved when the coil and the magnetic body come close to and go away from each other by controlling a current to be carried to the coil with a coil current carrying control unit, and a device for adjusting a position of the spring into the neutral position.
- 10. The running toy as claimed in claim 9,
wherein the device for adjusting the position of the spring includes an eccentric cam to receive a first end of the torsion spring, and a lever to adjust the position of the eccentric cam.
- 11. A running toy, comprising:
a steering device including first and second turning members; a connecting member to connect the turning members with each other; an electromagnetic force applying member to apply an electromagnetic force to move the connecting member; a current carrying control unit to control a current carried to the electromagnetic force applying member, so that the connecting member is movable between two steering positions; a torsion spring for urging the connecting member into a neutral position between the two steering positions, when the current is not carried to the electromagnetic force applying member; a suspension device to bias the turning members; and a device for adjusting a position of the spring.
- 12. A steering device for a toy, comprising:
right and left turning members to turn right and left steering wheels rotatably mounted thereon; a connecting member to connect the right and left turning members, an air core coil and a magnetic body, one of the air core coil and the magnetic body being located on the connecting member and the other being fixed on the toy, to use coil current to move the connecting member between at least two steering positions as the coil and magnetic body move towards/away from each other; and a torsion spring for urging the connecting member into a neutral position between the at least two steering positions, when no coil current is applied.
- 13. A steering device for a toy, comprising:
right and left turning members to turn right and left steering wheels respectively; a tie rod to connect the right and left turning members together; a coil to, upon receiving current, apply an electromagnetic force to move the tie rod in right and left directions, to turn the right and left steering wheels; a magnetic body to attract/repel the coil; a control unit to control current to the coil to cause the tie rod to move; and a torsion spring for urging the tie rod into a neutral position, when the coil current is halted.
- 14. A running toy comprising:
a steering device for the toy, including right and left turning units to turn right and left steering wheels, respectively; a tying member, to tie and move the right and left turning units into at least two steering positions; an air core coil stationary on the toy and a magnetic body movable with the tying member, which coil and body move the tying member in right and left directions when a current is applied to the air core coil, thereby moving the air core coil toward/away from the magnetic body; and a torsion spring for urging the tying member into a neutral position between the at least two steering positions, when the current is halted.
- 15. A running toy, comprising:
